2. Calls for Flamini to go are premature

The cruciate ligament tear he suffered at AC Milan mean he's not the player he was during his first Arsenal spell. In fact, he's not even got the same legs he had at the beginning of his second spell - but Flamini isn't finished.

Mikel Arteta and Santi Cazorla looked so vulnerable as a central midfield partnership in the defeat in Zagreb, it's no coincidence that Arteta - with Flamini at his side - looked more solid tonight against stronger opposition. And the two goals - his 12th and 13th for Arsenal over the two spells - prove there's life in the old French bulldog yet.

3. Debuchy is a shadow of his former self

You can forgive Mathieu Debuchy's nightmare performance against Dinamo Zagreb, if only because his teammates were awful too.

But to make Danny Rose look as good as he did on Wednesday evening will worry Arsene Wenger. Kieran Gibbs and Nacho Monreal have proven that just because you're out of the team, it doesn't mean you have to wallow in poor form.

Even accounting from the lack of cover he received from Joel Campbell, Debuchy doesn't look anywhere near his best.

4. Fazio doesn't belong in a team with top four ambitions

It was an evening littered with evidence of Federico Fazio's inadequacies. A personal favourite? When he passed to Giroud to set up an Arsenal attack and then in same phase of play Oxlade-Chamberlain managed to ghost past him despite tripping over his own feet and almost falling over.

He may not be first choice for Spurs, but Fazio wouldn't even be fourth choice at Chelsea, Arsenal, Manchester United or City - and that's the level Pochettino is trying to get to.

5. Oxlade-Chamberlain needs a run in the side

The former Southampton man is such a talent - you could see it in his footwork, in his vision against Spurs. In what was otherwise a largely flat Arsenal attack, Oxlade-Chamberlain was alway moving - and his movement was always unpredictable.

His passing could do with a bit of refining, but that will come with more minutes on the pitch. Wenger must find a way to get him into the first team on a regular basis.
